Description
Verfahren zum Gießen von Kugel- oder Rollenkäfigen Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Kugel- oder Rollenkäfigen.Method of casting ball or roller cages The invention relates to refers to a process for the manufacture of ball or roller cages.
Bekanntlich macht die Herstellung solcher Käfige außerordentliche Schwierigkeiten, da einerseits die Käfige fest genug sein müssen, um eine gute Führung der Kugeln und Rollen zu gewährleisten und deren Herausfallen verhindern müssen, andererseits durch Erfüllung dieser Forderungen Schwierigkeiten beim Einlegen der Kugeln oder Rollen entstehen. Ferner ist es wichtig, daß die Kugeln oder Rollen mit geringem Spiel und geringer Reibung in den Käfigen liegen. Die Herstellung der Käfige erfordert deshalb ganz besondere Sorgfalt.It is well known that the manufacture of such cages is extraordinary Difficulties, as on the one hand the cages have to be firm enough to allow good guidance ensure the balls and rollers and prevent them from falling out, on the other hand, by meeting these requirements, difficulties in inserting the Balls or rollers are created. It is also important that the balls or rollers lie in the cages with little play and little friction. The manufacture of the Cages therefore require special care.
Es ist bereits bekannt, massive metallene Rollenkäfige in der Weise herzustellen, daß der Käfig um die endgültigen Rollen als Kerne gegossen und die Zellen der Rollen durch radiales Auseinandertreiben der Rollen geweitet werden. Dieses Verfahren ist umständlich. Auch ist zu befürchten, daß die gehärteten Rollen durch das Erhitzen beim Umgießen mit Metall an Güte verlieren. Bei diesem Verfahren wird nicht die Elastizität, sondern die Bildsamkeit des Metalls in Anspruch genommen.It is already known to have massive metal roller cages in the way manufacture that the cage is cast around the final rollers as cores and the Cells of the roles are expanded by radial spacing of the roles. This procedure is cumbersome. There is also a fear that the hardened rollers lose their quality due to heating when pouring metal around them. In this procedure it is not the elasticity but the malleability of the metal that is claimed.
Erfindungsgemäß wird um als Kerne dienende Rollen von etwas größerem Durchmesser als die endgültigen Rollen ein massiver Käfig aus Kunsthorn oder einem ähnlichen Werkstoff gespritzt, dann werden unter Zuhilfenahme der Elastizität des Käfigs die Kerne aus ihren Zellen herausgedrückt und die endgültigen Rollen ebenfalls unter Zuhilfenahme der Elastizität in diese Zellen eingedrückt. Die Form, in welcher der Kugel- oder Rollenkäfig gespritzt wird, kann beliebig vielteilig sein und hat an ihrem Innenumfang gleichmäßig voneinander entfernte geringe Vertiefungen, deren Form sich nach der Form der Rollen oder Kugeln richtet und in denen die während des Spritzverfahrens als Kerne dienenden Kugeln oder Rollen in gleichmäßigen Abständen und genauer Flucht gehalten werden. Nach dem Erstarren des Käfigs werden die Kugeln oder Rollen aus dem Käfig herausgedrückt und die endgültigen Kugeln oder Rollen in die im Käfig entstandenen Zellen eingedrückt, was bei Verwendung von Kunsthorn infolge der großen Elastizität dieses Baustoffes sehr leicht geschieht.According to the invention, roles of something larger that serve as cores are used Diameter than the final rollers a massive cage made of synthetic horn or one similar material is injected, then with the aid of the elasticity of the The cage pushes the nuclei out of their cells and so does the final rolls pressed into these cells with the aid of elasticity. The form in which the ball or roller cage is injection molded, can be made up of any number of parts and has on their inner circumference evenly spaced apart small depressions, their Shape depends on the shape of the rollers or balls and in which the during of the spraying process, balls or rollers serving as cores at regular intervals and be kept more precise escape. After the cage has solidified, the balls become or rollers pushed out of the cage and the final balls or rollers pressed into the cells created in the cage, which is what happens when using artificial horn due to the great elasticity of this building material happens very easily.
Die Zeichnung zeigt in Abb. I eine Draufsicht auf ein Rollenlager, Abb. 2 einen Schnitt nach der Linie A-B der Abb. I, Abb. 3 eine Seitenansicht von Abb. I.The drawing shows in Fig. I a plan view of a roller bearing, Fig. 2 is a section along the line A-B of Fig. I, Fig. 3 is a side view of Fig I.
Um die in eine beliebig vielteilige Form in den üblichen Abständen eingesetzten Rollen wird ein kranzartiger Käfig I mittels eines beliebigen Spritzverfahrens gespritzt. Als Baustoff für den Käfig kann man Kunsthorn o. dgl. verwenden. Die Rollen haben einen etwas (beispielsweise 2/10 mm) größeren Durchmesser als die in dem Lager zu verwendenden endgültigen Rollen 2. Nach dem Erhärten wird der Käfig mit den Rollen aus der Form genommen und werden die Rollen aus dem Käfig herausgedrückt. In die hierdurch frei gewordenen Zellen werden die endgültigen. Rollen 2 eingedrückt.To that in any multipart form at the usual intervals A ring-like cage I is created using any desired spraying process injected. Synthetic horn or the like can be used as the building material for the cage. the Rollers have a slightly (e.g. 2/10 mm) larger diameter than those in the bearing to be used final rollers 2. After hardening, the cage taken out of the mold with the rollers and the rollers are pushed out of the cage. The cells that become free become the final ones. Rollers 2 pressed in.
